Project description:RNA-seq of human hepatocellular carcinoma cell line Huh7 and immortalized hepatocyte cell line THLE5B treated with experimental compound AD80, Sorafenib, and vehicle for 24 hours
Project description:Cyclin D3 is critical hematopoiesis and loss of cyclin D3 leads to resistance to transformation of bone marrow progenitors by Notch1-IC. We used a small molecule targeting cyclin D3:CDK4/6 activity to study whether its inhibition is an effective therapeutic strategy. We analyzed T-ALL lines in vitro with PD-0332991 or vehicle control to determine genes affected by the drug. CEM, Jurkat, DND41, and CUTL-1 cell lines were treated with 1 uM PD-0332991 or DMSO for 15 hours prior to RNA extraction and hybridization to Human Genome U133 Plus 2.0 Affymetrix arrays.
Project description:D-cyclins represent components of cell cycle machinery. To test the efficacy of targeting D-cyclins in cancer treatment, we engineered mouse strains which allow acute and global ablation of individual D-cyclins in a living animal. Ubiquitous shutdown of cyclin D1 or inhibition of cyclin D associated kinase activity in mice bearing ErbB2-driven mammary carcinomas halted cancer progression and triggered tumor-specific senescence, without compromising the animals' health. Ablation of cyclin D3 in mice bearing T-cell acute lymphoblastic leukemias (T-ALL) triggered tumorspecific apoptosis. Such selective killing of leukemic cells can be also achieved by inhibiting cyclin D associated kinase activity in mouse and human T-ALL models. Hence, contrary to what one might expect from ablation of a cell cycle protein, acute shutdown of a D-cyclin leads not only to cell cycle arrest, but it also triggers tumor cell senescence or apoptosis, and it affects different tumor types through distinct cellular mechanisms. Inhibiting cyclin D-activity represents a highly-selective anticancer strategy which specifically targets cancer cells without significantly affecting normal tissues. A human T-ALL cell line KOPTK1 cells were cultured in the presence of the CDK4/6 inhibitor PD 0332991 (PD; 1 microM) or vehicle (VO) for 48 hrs. Experiment was done in biological triplicate. A total of 6 RNA samples (3 vehicle treated and 3 PD 0332991 treated samples) were used for microarray expression analysis.
Project description:The aim of this study is to estimate gene expression variations involved in glucose meatbolism in HepG2 cell line after cell cycle(G1 to S phase) inhibition by using drug(PD-0332991) or CDK4-6-knock down. We hypothesized that transition of glycolytic gene expression might indicates the effect of PD-0332991 drug treatment in Hepatocellular carcinoma cells.
